2017 Map of Loony Hollow

About this map

O'Fallon Cr winds through the northern reach of this Montana landscape, where the boundary between Prairie County and Custer County divides the terrain. The map centers on the distinctive namesake Loony Hollow, a landform defined by a complex network of seasonal drainages including Ash Cr, Dry Cr, and Whitney Cr. Evidence of rural water management is prominent in the upland sections, marked by features such as Horse Reservoir and Archdale Reservoir. In the southwest, the named settlement of Shoemaker stands as a focal point for local history research. The presence of Ismay Rd in the northeast corner provides the primary modern transport link across this drainage-rich territory, which remains dominated by the Township and Range survey system, including t10n r54e and t9n r53e.
